QConSF 2025 - Developing Claude Code at Anthropic at AI Speed

Anthropic's development of Claude Code at AI speed, where 90% of production code is powered by AI, marks a significant milestone in the integration of artificial intelligence in software development. This achievement was showcased by Adam Wolff at QCon San Francisco 2025, highlighting the focus on speed over planning in Claude Code's design. For website owners, this means that the AI-powered tools and services they use may soon be developed and updated at an unprecedented pace. As AI takes over a larger share of production code, website owners can expect more frequent updates and new features in the tools they rely on. However, this also raises concerns about the potential for increased errors or inconsistencies in AI-generated code, which could impact website functionality and security. To stay ahead of these changes, website owners should prioritize AI bot tracking and monitoring to quickly identify and respond to any issues arising from AI-generated code. They can also review their llms.txt files to ensure they are up-to-date and accurately reflect the AI-powered tools and services used on their websites. Additionally, website owners should consider implementing automated testing and validation procedures to catch any errors or inconsistencies in AI-generated code before they affect their website's performance.
